You can see if the clock is enabled by running:

I just realized if you can't boot, you can't do this. :-/
I can boot with the latest set in your git repo, but the Ethernet
doesn't apparently fully operate. I don't get errors, but I cannot
get a dhcp address.
I'll try to do a more exhaustive test later today to get an idea of
what works and what doesn't. When I ran my basic tests, I just did a
feel-good boot test (and reboot test)

FYI: manually calling clk_prepare_enable() in the davinci_mdio driver
seems to at least fix the ethernet. In master branch it's done by
pm_runtime_get_sync() (in davinci_mdio_reset()). However I'm still
getting several oopses and WARNs so there's some more work to do.
Hmm... I'm wondering if we need to also add #power-domain-cells to the
PSC clocks and power-domains properties to the consumers.
For this specific case though, it seems strange to me that the drivers
to clk_get() and clk_get_rate() but never enable the clocks.
Also, are the oopses and WARNs the same as before?
